The Lowdown
Alright, Rusty here, let's talk about what's cooking.
Right now, there’s a bit of a wait, but things get going on Wednesday afternoon, July 15th, at Jaconé. It’s not the best start—we’ve got 6ft of swell from the SE with a 10-second period, and the combined energy is moderate at 667. The wind is cross-off from the E at 19 mph, so it’s clean enough, but the tide conditions are making it a bit of a head-scratcher. The water temp is sitting at 72°, which is pretty much average for this time of year.
Thursday morning, July 16th, is where it gets interesting. We’ve got NE offshore wind at 9 mph, and that’s a major plus—clean lines all the way. Swell drops a little to 4ft, still SE at 10 seconds, energy down to 444, but the forecast says *expect good surf conditions*. That’s your call to get out there early. Thursday afternoon the wind shifts a bit and the quality fades.
Friday, July 17th, morning is another winner: light NNE offshore at just 6 mph, 3ft SE swell, period still a solid 10 seconds, and energy at 368. It’s small but clean, perfect for a longboard or a funboard. The break is consistent and intermediate-level, so it won’t be too crowded, though it gets *sometimes* busy.
The real standout, the one you circle on the calendar, is Tuesday, July 28th. Morning session: 8ft of S groundswell with a very long 15-second period. The energy is massive at 2463—that’s strong. Wind is light offshore from the NE at 6 mph, creating glassy, clean conditions. This is excellent surf, but at 8ft, it’s pushing into expert territory. The swell direction from the S is right on the money for Jaconé’s optimum SE exposure. The afternoon holds 7ft with similar quality. Crowds are *sometimes* an issue, but on a day like this, the trade-off is worth it.
Before that, Sunday, July 26th, morning looks solid too: 5ft S swell at 10 seconds, clean cross-off wind from the ENE, energy at 588, and the forecast calls for *very good surf conditions*. Monday, July 27th morning is even bigger at 6ft S, 11-second period, and a moderate offshore from the ENE—another one for the intermediate to advanced crew.
After the 28th, Wednesday, July 29th is still good: 5ft S swell at 12 seconds, morning offshore from the NNE, energy at 750. But Thursday, July 30th, falls apart with strong onshore wind and rain—a definite skip.
There’s a long gap of ordinary, small surf from Friday, July 24th afternoon through Saturday, July 25th, with poor conditions and onshore winds. Just sit that out.
Bottom line: the best on offer is Tuesday, July 28th morning at Jaconé. Big, clean, powerful groundswell with light offshore wind. That’s the one to plan for. Thursday the 16th and Friday the 17th mornings are your smaller, cleaner windows early on.
Stay stoked,
Rusty

Information about the Jaconé Surf forecast
The above surf forecast table for Jaconé provides essential information for determining whether the surfing conditions will be good over the next 16 days. A general guide to surfing at Jaconé can be found by selecting the local surf guide option on the grey menu. Our Jaconé surf forecast is unique since it includes wave energy (power) that defines the real feel of the surf rather than just the height or the period. If you surf the same spot (Jaconé) regularly then make a mental note of the wave energy from the surf forecast table each time you go. Very soon you may start to choose your surf days based on the wave energy alone combined with our forecast of favourable offshore wind conditions. Our star ratings will help here and of course you will also find the usual wave height and period predictions on our surf forecasts as well as a full break down of the swell components under our advanced users option (to reveal that, click the little Einstein character under the tide times).
Further information to help with frequently asked questions about our surf forecast for Jaconé may be found under the help tab on the top menu and also by moving your mouse over the question marks on the surf forecast table itself. Please always bear in mind that the forecast is for near-shore open water and local factors at each surf break influence the actual breaking wave height, such as the beach / reef profile, water depths offshore and shelter.
Jacone is 14 km (9 miles) from the city of Saquarema. If you plan a holiday in Rio de Janeiro, look for hotels and other accommodation in Saquarema. Saquarema has rooms for a wide range of budgets as well as car hire and transport links.
